t-SNE node shows missing rows.

Hello,
I was able to run my first workflow today. Trying to upload a different set of data, I encountered the following issue in t-SNEnode. Do you have any idea where the issue could be? I have uploaded an image showing the error.
Thanks for your support!

Have you tried filtering rows with missing values upstream? This may alleviate the problem in the t-SNE node. Just a guess. I’ve never used the node. If it passes them on I don’t think the k-Means will work properly.
